It looks as if that Twins sequel is moving forward. Deadline reports that The Book of Mormon star Josh Gad and Ryan Dixon have been tapped to pen the treatment for Triplets, with Dixon handling the script. The follow-up has Arnold Schwarzenegger and Danny DeVito reprising their roles from the 1988 comedy as mismatched siblings. As previously reported, the follow-up will find them getting in touch with a third brother played by Eddie Murphy. Hit the jump to see what Schwarzenegger told us about the sequel when we spoke to him on the set of the upcoming actioner The Last Stand.

We talked with Schwarzenegger on the set of The Last Stand earlier this year, and he was enthusiastic about Eddie Murphy joining in on the fun, even throwing up some marketing suggestions while he was at it:

“I’d find somebody like Eddie Murphy or someone [laughs] that people would say, ‘How does that happen, medically speaking?’ and, ‘Physically, there’s no way.’ Then somehow we would explain it. That would be hilarious with what we know about someone like him. You’ve got to find people that, in real life, people laugh about them and whatever we know about them that makes you laugh. I can see a poster, a billboard, with us three… ‘They found another one. Triplets. Only their mother can tell them apart.’ I would do that in two seconds, because that’s real entertainment. You come out with that movie for Christmas, like December 5th or something like that, and you’re home free, just like with the other one.”

Twins director Ivan Reitman is poised to return to helm Triplets, but we likely won’t hear more on the project until Gad and Dixon finish the treatment.
